SAMUEL E. WINDER, OF SALEM, NEW JERSEY, ASSIGNOR OF ONE-HALF TO J. EALE l)I L- WORTH, OF SALEM, NEW JERSEY.

BOTTLE-BLOWING MACHINE.

To all whom it may concern:

Be it known that I, SAMUEL E. WINDER, a citizen of the United States, residing in Salem, in the county of Salem, State of New Jersey, have invented a new and useful Bottle-Blowing Machine, of which the following is a specification.

This invention relates to a maehine for making glass bottles and more particularl that type of bottle havinga long narrow neck and has for an object to provide a bottle former in which the amount of material to be used in the formation thereof may be accurately determined for each bottle and the material so shaped as to produce a substantially uniform thickness in the completed bottle. Heretofore in the manufacture of bottles of this type the proper shaping of the material previous to the blowing operation, has required a large amount of hand manipulation to properly distribute the molten glass so that when air is forced into the neck it will act against an even thickness of glass and will produce a bottle with a long neck.

It consists of a novel means for forming the neck of a bottle with an aperture in the same so that when pressure is admitted into said aperture, it will be exerted downwardly and outwardly and will cause the moltenmetal to expand and completely fill the mold in which it is located at this time.

It further consists of a mechanism for working and shaping the body of the material aftcr the neck and mouth ofthe bottle have been formed, so that the contour of the material may closely approximate that of the bottle which is to be blown therefrom, so

that under internal-pressure this shape will.

practically remain the same, since the ex pansionof all parts will be very nearly equal.

It further consists of other novel features of construction, all as will be hereinafter fully set forth.

Figure 1 represents a side elevation partly in section, of a machine embodying my invention. Fig. 2 represents a plan of the Fig. 3 represents an end elevation of manually operated portion of the machine. Fig. 4 represents a side elevation of the centrifugal roller mechanism. Fig. 5 represents a detail of the feed operating plunger. Fig.

tory and reliable results, although it is to be understood that the various instrumentalities of which my invention consists can be variously arranged and organized and that my invention is not limited to the precise arrangement and organization of these instrumentalities as herein set forth.

1 designates a standard mounted on a suitable base 2, which may, if desired, be carried by wheels 3 in order that the device may be conveniently moved from one part of a shop to another. The standard 1 carries thereon a head 4, which is mounted on a suitable bearing 5 so that it may have a movement relative to the standard 1. The head 4 is preferably rovided with a shoulder in order to receive t ereon a table 6 provided at suitable intervals in the surface thereof with apertures 7 adapted to receive a bottle neck former 8. The openings Tearry the formers 8 forward as the table 6 is revolved step by step, so as to bring them into proper position to be engaged by a cooperating portion of the machine at the correct time. In order to rotate the tablet; to perform this step by step operation, lugs 9 are secured in any well known manner to the table 6 and located approximately the sameangular distance apart as the o enings 7 and are each adapted to be engagec by a pawl 10 pivotally secured to an extension 11 of the head 4, so that it will be intervals correplponding to t e openings 7 and are adapte to cooperate with a locking pin 14 so that the parts may be pro erly set in correct relation with respect to t ier parts of the machine. This stop pin 14 is slidingly mounted in a projecting bracket 15, preferably formed integral with a hub 16 forming a part of a frame 17 carried by the base 2; The hub 16 has rearwardly extending wings .18 forming opposite sides of a slot 19 and slidingly mounted within which slot is a le- 0 ver 26 carried by a pivot 21 on the wings 18. This lever 20 is in operative engagement with the sliding pin. 14 through the medium of a recess 22 in the side of the pin 14, whereby as the lever is swung downwardly the pin 14 will have a corresponding movement. A spring 23 is fixedly secured at one end to the bracket 15 and at the other is connected to a pin 24 carried by the pin 14 and projecting through a slot 25 in the sides of the bracket. It will be clear, therefore, that as the lever 20 is depressed the in 14 will be withdrawn from one ofthe ocking apertures 13, thus releasing the table 6 so that upon a movement of the head 4 it may rotate a portion of a revolution and as soon as the lever 20 is released the spring 23 tends to return the pin 14 to normal position again, which occurs when the next adjacent aperture 13 comes into the path of movement of the upwardly pressed locking pin 14.

26 designates a hollow piston having a stem 27 formed integral therewith, the former being adapted for a sliding movement in the hub-member 16 and the latter having a guide block 28 suitably ositioned relative thereto. A portion of t e stem 27 is rovided with a thread 29 for the purpose of receiving adjusting nuts 30 whereby the upward movement of the hollow plunger 26 may be limited and varied as desired. Between the guide block 28 and the adjusting nuts 30 a spring 31 is provided, which normally tends to maintain the hollow plunger in normal position. The function of the hollow plunger is to raise the former 8 from its position in the opening 7 in the table 6 at I a certain time in the cycle of operations.

Of course provision must be made 1n the hollow plunger 26 for the lever 20 assing through the hub 16 and therefore slots 32 are cut on o posite sides and in alinement with each otlier to permit correct operation of the aforesaid lever.

33 designates a slotted guide block located within the hollow lunger 26 and adapted to be engaged by t e lever 20, whereby a plunger 34 having an end suitably shaped to punch a hole of the proper diameter in the neck of a bottle is operated. This plunger is provided with a flanged head 35 abutting which" is a spring 36, the tendency of which is to hold the plunger 34 well within the hollow plunger 26. A guide block 37 is seated on the hollow plunger 26 and serves to direct the plunger 34 into the neck of the bottle forming material, the external diameter of the block 37 being of a width corresponding to a seat in the neck former 8.

It will be apparent that as the lever 20 is given a downward movement that besides withdrawing the locking pin 14 from the table 6, the hollow plunger 26 will also be moved downwardly so as to be withdrawn entirely below the table 6 and the spring 31 thereby put under compression. As soon as the lever is released this spring 31 will tend to return the hollow piston to its operative position and. in order that it may not contact with the bottom of the table 6, thus producing a braking effort thereon, a stop memher 38 is suitably pivoted to the hub 16. This stop member 38 is provided with oppositely disposed arms 39 and 40, the former being adapted to prevent the upward movement of the lever 20 and the latter being adapted for successive engagement with each of a series of stops 41 suitably located at intervals about the periphery of the table 6. In the present instance a spring 42 is provided to maintain the arm 39 in locking en- 9 gagement. As soon as the lever 20 reaches its lovvermost position the spring 42 immediately swings the arm 39 above the lever 20 and thereby prevents a spring 31 from returning it to normal position when the oper- 'ator releases the same. It is, however, necessary to have the hollow plui'igcr return to normal position at a definite time in the cycle of operations and therefore the stops 41 are so position ed that one of them will engage the trip arm 40 and release the locking arm 39 at this predetermined time, whereby the hollow plunger immediately makes its return movement. The function of the plunger 26 is to remove the neck former 8 from the table 6 and the former is therefore provided with a seat 43 of a diameter corresponding with the extension 44 of the guide block 37. The former 8 is provided with a circumferential groove 45 adapted for locking engagement with a clamping member to be presently described, while the interior of the former 8 is so shaped as to form the pattern for the neck ring of a bottle. A clamping member 46, preferably formed in two parts pivotally secured together and operated by suitable handles 47, is provided and is ada ted to be clamped on the neck former 8 so t at the same may be moved from one part of the machine to the other while in its heated condition.

48 designates clamping jaws provided with a gather receiving opening 49 and having bell crank extensions 50 formed integral therewith and pivoted at a point 51 so that as the extensions 50 are thrown outwardly the clamping jaws 48 will be drawn out, and vice versa. This movement is produced in any desired manner, but in the resent instance a head 52 is secured to the ell cranks by means of links 53, whereby a toggle like joint is effected and the head 52 is'connected by piston rod 54 with the operating piston 55. Inthe present instance the piston rod 54 is hollow in order to convey motive fluid'to one side of the piston 55, as indicated by the inlet port 56. The piston 55 is guided and operated by the mechanism now to be described.

57 designates a standard mounted on the base 2 and carrying thereon the cylinder 58 at a suitable point on the interior of which is located a cam roller 59 adapted for engagement with a cam groove 60 of a piston rod'6] This piston rod 61 passes through the cylinjder 58 and enters a cylinder 62 securely bolted to the cylinder 58 and of such an internal diameter as to receive a piston 63 affixed to the piston rod 61. One end of the piston rod 61 is counterbored as shown at 64 to receive the piston 55, a suitable plate 65 being provided to close the cylinder opening and forming a stuiiing boX through which the piston rod 54 operates. This plate 65' is provided with extension members 66 throu h the ends of which the pivot in 51 of tie clamping members passes and t ereby firmly supports the entire aw structure. A port 67 is provided at a suitable point in the piston r0 61 so as to communicate with the opposite side of the piston 55 from the inlet port 56, thereby providing means for reciprocating the said piston.

Attached in any desired manner to the side of the cylinder 58 is a casing 68 inclosing a slide valve structure of ordinary ty e, the motive fluid inlet to n hich is indicated at 69 and the delivery ports 'by the pi cs 70 and 71. A valve 72 controls the a mission of motive fluid to one or the other of the pipes 70 and 71, the o eration of which is accomplished by a lin 73 attached to the slide valve 72 and joining a rod 74, which passes through the cylinder 62 and to the end of which is secured a tri arm 75 that passes through the head ofscy inder 62 and into the cylinder a sufficient distance to be engaged by the piston 63 on one of its strokes. A

second-trip arm 76 is secured adjacent to the bracket 73 and passes through the op osite end of cylinder 62 a like'distance to e engaged by the piston 63 when it is at that end of the other stroke. It will be clear therefore that the slide valve 72 is always in position to deliver motive fluid from the inlet 69 to one or the other of the pipes 70 and 71 the selection of which is determined by the position of piston 63 77 designates a cylinder substantially of similar construction to the cylinder 68 and with which the pipes'70 and 71 communicate at the same point. A slide valve is located within this cylinder 77 and o erated by a connecting rod 78, preferably joined by a link 79 to a part operated by the lever 20. Pipes 8O and 81 communicate with the interior of the valve casing 77 and connect the same with o posite ends of the c linder 62 so that when tl ie valve controlled y the rod 78 is in one position the air will pass through pipe 81 into cylinder 62 and drive the piston in one direction and when the valve is reversed the pipe will become filled with motive fluid and drive the piston 63 in the opposite direction.

also shifted the motive fluid will immediately be supplied through the pipe 80 to return the piston 63 to the opposite end and when at the end of its back stroke it will of course contact with trip arm 75 and thus shift valve 72 to bring about a repetition of the step just described. As the piston 63 moves one way or the other the connected )iston rod 67 of course isalso carried bac 'ward and with it the attached parts carrying the clamping jaws 48. This action of the clamps 48 carries the neck former 8 away from the table 6 and into close roximity to a supporting plate 82 provide with an opening 83 of a iameter suilicient to grasp the neck former 8 by the grooved portion'45. This plate is secured in any suitable manner to a standard 84 in the present instance being adjustable thereon by means of a sliding connection formed by set screws 85. It will be noted in the position shown in Fig. 1' that the movement of the clamping jaws 48 toward the plate 82 would not bring the neck former 8 in proper position relative to the plate 82 but instead would be at approximately the length of a bottle below the same and therefore in order to bring the parts together and thereby position the neck former correctly for the succeeding steps, the cam slot 60 in the piston rod 61 is rovided. The function of this part will be c ear for as the piston rod 61 makes a movement the cam roller 59 engages With the slot 60 and thereby imparts a partial turn to the clamps, this inverting the osition of the neck former 8. As soon as t e clamps 48 have been given this turning movement themotive fluid is admitted back of the small piston 55, giving a longitudinal movement of the piston rod 54 and o crating the toggle connection to release t e clamps so that the former 8 is thereby accurately laced in the opening 83 of the plate 82. upply pi es 86 and 87 are provided to supply fluid cm the valve chest 68 to the opposite sides of the piston 55 and are preferably of a flexible nature to allow of the v reciprocating movement.

' 88 designates bearing brackets oined to opposite sides of the cylinder 58 and are pro-' vided to receive rods 89 which pass through the head of cylinder 62 into the interior thereof into the path of movement of iston .63. The opposite ends of these ro s are fastened in any desirable manner to a collar 90 loosely mounted on piston rod 61 and to this collar is bolted the operating link 12 of the head 4. The manner in which this return is effected will now be clear, since as soon as the piston 63 strikes the projecting rods 88 the collar 90 will move back in unison with the piston 61 until at the end of the stroke the pawl 10 is dro ped behind the lug 9. At this time the neck former 8 is deposited on the plate 82 and the return stroke begins, whereupon the shoulder formed by the plate 65 immediately abuts the collar 90 and carries it forward, thus advancing the pawl 10 and artially rotating the table 6.

Located a jacent the standard 1 on the base 2 is a bracket 91, forming bearings 92 for a shaft 93 normally maintained in rota tion by a pulley 94 thereon and which may be driven y any suitable'well known mechanism. Pivotally secured to the shaft 93 for rotation therewith is a head 95 having on either side wings 96, to each of which is pivoted a bell crank 97 carrying at one end a ro1ler798 and-at the other end a spindle 99. These spindles 99 are preferably provided at either end with a ball run way 100, whereby a bearing is formed between the spindles 99 and a tubular roller shaper 101. It will therefore be seen that the tubular roller sha ers are capable of a rotary movement entirely independent of the movement of the spindles 99, which are of course revolving on the shaft 93. Particular attention is directed to the function of these rotary shapers, since the configuration of the finished bottle substantially depends on their action, as also the production of a bottle of uniform thickness. The surface of these shapers is comparatively at a low temperature with res ect to that of the molten glass and therefore as soon as the partially formed bottle is placed between the shapers and contacts therewith it will immediately become chilled and the entire surface be hardened for a very slight depth. Within this outer shell of hardened glass is a layer of molten glassin a yielding state, which is readily acted upon by air pressure and. consequently as soon as this pressure is applied through the neck of the partially formed bottle, the outer chilled surface gradually expands in a uniform manner. It will thus be clear that the correct shape of the bottle is maintained, there are no irregularities in the surface thereof and it is of uniform thickness throughout, all of which are essential, desirable qualities in the manufacture of glass bottles of this type.

102 designates a sleeve slidingly mounted on shaft 93 and provided with a cone surface 103, the function of which is to force outwardly the rollers 98 and consequently the bell cranks 97, whereby the spindles 99 and sha ers 101 are brought together. Return of t ese parts to their normal position is ac complished in any desired manner, in the present instance by means of a spring 104 ]oining the two bell cranks 97 at a point adjacent the rollers 98. The shiftmg of the sleeve .102 is accomplished preferably by a collar 105 secured in a groove of the sleeve and engaged by a forked end 106 of a lever 107 suitably ivoted to the bracket 91. The operating end of the lever 107 is connected to a iston rod 108 through the medium of a lin k 109, the said piston rod being operated by fluid pressure admitted to cylinder 110 at. stated intervals. nicate with opposite ends of the cylinder 110 and are connected directly to pipes and 71 of the main motive supply passing through the valve member 68. Suitably supported Pipes 111 and 112 commuon bracket 91 is an upright 113 adapted to support a plate 114 directly above I the sha ers 101, the said plate being provided wit an opening 115 of sufficient diameter to allow the insertion of the partially formed bottle, the clamp 46 restingdirectly on the adapted whe'n closed, to orm a mold for the bottle which is to be blown. The adjacent parts of the machine have already formed the neck and neck ring of the bottle with an o ening therein, and the remaining ortion o the gather, after manipulation y the shapers, is ready for the blowing operation, which takes place assoon as placed in the molds 118. These molds are of course clamped together and an air pressure head brought down over the mouth of the partially formedbottle and as soon as the air is admitted the material is blown immediately to the correct bottle shape.

The operation of -my machine is as follows :Two operators are preferably employed in the manipulation of the machine, operator A standing adjacent the mold table 116 and operator B in position by lever 2-0. 120

77, from which it passes to pipe 81 and is admitted to the c inder 62 to actuate piston 63, which at this time is in the position indicated in dotted lines in Fig. 1. This pressure forces the iston 63 out on its forward stroke, near t 1c end of which it conready for a repetition of the steps just de-' valve in cylinder 77 to admit pressure to the pipe-80. At this time piston 63 has reached the end of its forward stroke as indicated in dotted lines in Fig. 2 and has operated trip arm 76 to shift the position of valve 72 and allow the pressure to pass through pipe 70 to valve chamber 77 and thus by pipe 80 to the rear of cylinder 63 to make its return stroke. This piston 63 is thereupon forced to the other end of the cylinder 62 and carries the plate 65 and bracket member 66 with it and into contact with the collar 90 so that the latteris also moved forward and brings the pawl 10 into engagement with lug 9 to rotate the table a su flicient distance to bring one of the formers 8 directly over the plunger 26. The lever up to this time has been eld in the lower position throu h the catch 39, which has been shifted by t re spring 42 and thus maintains the parts locked during the rotation of the table 6. As soon as one of the tri ins 41 on the table 6 engages the arm o t e catch lever, it removes the lat ter from locking engagement, whereupon the spring 31 quickly returns the lever 20 and hollow plunger 26 to normal position. This is best shown in Fig. l, the ends of the plunger passing through the opening 7 in the table a sullicient distance to raise the neck former 8, which is of course picked up in the passage of the plunger through the opening. As 'soon as the former 8 has reached this position, it is in place to be accurately engaged by, the clam ing receiver 48, which is at this time broug' t into closed position by a rearward movement of piston 55. The return of piston has in the meantime occurred through the admission of air by the conduit 87 and hollow piston rod 54.

The position of the receiver 48 at this time is shown in Fig. 3 and the molten glass is poured thereinto. Operator A now gives lever 20 a slight upward moveinent to raise the plunger 34, thus forming an opening into the neck of the bottle of some considerable depth,

having accomplished which the machine is scribed. It W1 1 be noted that when the piston 63 reaches the extreme end of cylinder 62 on the return stroke, that is as indicated in Fig. 1, that the trip arm 75 will be oper-' ated to shift the valve 72 so as to restore these parts to their initial position. Of course it will be understood that during the reciprocation of the piston 63 that the parts attached to the piston rod 61 are being operated to 1perform another ste that of conveying t e partially formed ottle from this position on the table 6 to the plate 82. It

will be clear that as the piston rod 61 makes its forward stroke that the cam slot 60,

through engagement with the cam roller 59,

will give a half turn to the receiver 48, whereby the neck former is inverted and deposited in place on the plate 82. Just at the instant that the receiver comes into position adjacent the plate 82, air has a free access behind the piston 55 and forces the same outwardly a suflicient distance to release the formers from clamping position, thereby leaving the neck former and the molten'material attached thereto in position on the plate 82. As the clamps are released the piston 63 o erates trip 76 to change the direction of t e flow of air from the valve 77 and the movement of piston 55 is reversed to bring the members 48 together into receiving position. Operator B now removes the neck former 8 from this plate and inserts the partially formed bottle still in a heated condition through the opening 115, between the shapers 101. At this stage the shapers are in open position as shown in Fig. 4, since the pipe 112 is in communication with the pipe 70 and valve rod 108 raised to operate ever 107 and lower the slide sleeve 103 so that the spring 104 may draw the bell cranks together at their lower ends and project the spindles 99 outwardly.

It will of course be understood that during .100

the time that the shapers are in open position operator A is removing the partially molded bottle therefrom and placing the same in position in the blow mold mechanism and operator B takes the deposited neck former 1 5 from the plate 82 and drops the gather through theopening 1.15 between the shapers in the place of the one which has just been removed. These shapers are open a sufficient time to allow conveniently both of these operations, since they are held in open position during the entire forward stroke and then remain closed, shaping the molten glass during the return stroke of piston 63.

Attention is called to the rotation of the shaft 93 carrying the spindles on which the shapers 101 are mounted, as this rotation 1s continuous whether the shapers are in open or closed osition.

It will erator A has removed the material from t e shapers, operator B takes another neck former. from the machine and places it be tween the rollers and operator A places another neck former in a recess 7 of the 125 table 6.

In Fig. 8 the first ste of the machine 18 well illustrated, the gat 1er of glass having been molded by the neck former 8 and an opening has been punched therein for the ad- 1 3 0 e understood that as soon as op the shape and thickness of the completed mission of air at the proper time. Fig. 9 represents the next step in the operation, wherein the molten material of Fig. 8 has been drawn out and rolled in the revolving portion of the machine. As soon as the glass has assumed this latter shape it is ready for the blow molding machine in-which it is placed by 0 erator A and the clam s securely locke around it so that when t e air pressure head is brought down over the mold of the bottle, there will be no escape for the pressure and the same will be forced into the opening in the neck of the bottle. This pressure acting upon the mass of red hot yielding glass, will expand the same to fill the mold and produce a bottle of the size and shape desired. It will be understood that bottle epend largely upon'the effect roduced by the contact of the molten g ass with the chilled surface of the rollers 101.
